I had blood work done this morning. Everything came back looking good, especially my creatinine level: 0.97. That's the lowest it's been in years.
I also had a kidney scan yesterday. It was pretty cool because I could watch it in real time. They injected me with a lot of fluids with radioactive isotopes. I could watch my kidneys fill with fluid and then watch the fluid leave the kidneys and fill the bladder. I read the results and it read very positive. I haven't heard from any of my doctors about their interpretation. Here's what I read:
History: 56 year-old male with a history of left renal obstruction secondary to lymphoma involving the left perinephric region diagnosed in June 2015, with proximal left ureteral narrowing demonstrated on cystoscopy and ureteroscopy, followed by left
ureteral stent placement and subsequent removal; assess relative renal perfusion and function and assess for obstruction
Comparison: CT scan of the chest, abdomen and pelvis 8/24/2015
Technique: A flow study was performed following intravenous administration of the dose. Sequential images were then obtained for 30 minutes. Time-activity curves were generated from background-corrected renal regions of interest.
The patient was injected with 40 mg of furosemide intravenously, and an additional 30 minutes of imaging was performed.
Wash-out curves were then generated from background-corrected renal regions of interest.
Findings: The flow study demonstrates minimally delayed, but symmetrical perfusion to both kidneys, which appear normal in size. Serial static images demonstrate prompt initial uptake bilaterally, with normal tubular transit time and prompt excretion
into the bladder. There is only minimally prominent uptake of the calyces and right renal pelvis, with visualization of activity within both ureters, and with progressive partial clearance of activity from the upper collecting systems bilaterally
throughout the remainder the baseline study. Further partial clearance is noted on an upright post-void image. Quantitative analysis demonstrates no significant asymmetry in renal function. Post-diuretic images demonstrate prompt clearance of remaining
activity from the upper collecting systems bilaterally, with normal clearance half-times from the left and right kidneys of 9.2 minutes and 5.8 minutes, respectively. These values are valid, despite the fact that the patient was unable to tolerate the
entire diuretic imaging sequence. There is minimal cortical activity bilaterally remaining at the conclusion of the study.
IMPRESSION: There is essentially normal renal perfusion and function bilaterally, as described above, without significant asymmetry noted. There is minimal prominence of the upper collecting systems initially, but there is no evidence of significant
drainage impairment on either side. See above.
